Abstract

Formet ladning for effektiv overfor- ing av energi fra et eksplosivt materiale (12) for dannelse av en stråle, idet virk- ningen fra sjokk-refleksjonene på strålen reduseres. Den formede ladning omfatter en første foring (22) som ligger inntil det eksplosive materialet (12) og minst en annen foring (24) med et hult senter. Kombinasjonen av de to (eller flere) for- inger reduserer virkningen som sjokk- refleksjonene har på ladningen, og øker dermed strålens enhetlighet og dens mål- gjennomtrengende evne. Den første og andre foring (22,24) kan utformes som en sammen- satt foring (20,40) med minst to forings- elementer som strekker seg utover fra for- ingens topp-punkt. Flere foringer kan likeledes være plassert inntil den andre foringen på en kaskade-forbundet måte, eller det kan foreligge et gap mellom nær- : liggende foringer. Et støtabsorberende materiale kan være anbragt mellom forings- elementene for ytterligere å dempe sjokk- refleksjonene. Alternativt kan slike gap fylles med et eksplosivt materiale for å øke strålens masse. Den ene foring kan være kortere enn den andre foring for å produsere en segmentert puls i strålen.
